PROBLEM TO BE SOLVED: To provide a pump system for regulating pumping of a fluid to, for example, a medical instrument such as a wound bed surgery device.SOLUTION: A coupling system for receiving a push rod includes an internal channel having a sloped wall, and a piston received within the internal channel. The piston includes at least one flexible member arranged within the internal channel to be acted upon by the sloped wall to engage the push rod. The only external force required to couple the push rod is an axial force on the piston in a prescribed direction. The only external force required to de-couple the push rod is an axial force on the piston in an opposite direction. |
